Deadliest Catch

After a devastating 2011 opilio season, every ship in the fleet -- including two new boats -- is looking to make a comeback in 2012 for king crab season.

It's cloak and dagger time on the Bering Sea as Keith and Junior form -- and break -- a covert alliance.

On the blue crab grounds, competition leads to more deceit among the captains. Serious injuries plague the fleet, and Junior's betrayal of his alliance with Keith comes back to haunt him with potentially lethal consequences.

On the blue crab grounds, a showdown between the Saga and Seabrooke takes an unlikely turn. On the Northwestern, Captain Sig must make a decision about his brother's future, and the Time Bandit has a close call in False Pass.

Change is in the air on the Bering Sea just five weeks into king crab season. Big moves are made on some boats while it's the same old story on others. Still, the hunt for the elusive blue crab is on everyone's radar.

On the Northwestern, Jake's dark secret sets off a fistfight that throws Edgar's new captaincy into jeopardy. Tempers flare on the Saga and Seabrooke when Elliott grows wise to Junior's devious ways.

Life-changing decisions are in the air as king crab season comes to an end. Young Jake Anderson struggles with his decision to leave the Northwestern, and Josh Harris plots to buy his father's old boat.

Skippers and crews lace up for moneymaking opilio season and come to terms with all they leave behind. An accident on the Time Bandit has them racing for shore, and Jake Anderson gets a not-so-warm-welcome on his new boat.

A Category 4 storm has landed on the fleet two weeks into opilio snow crab season. As the first pots come aboard, some captains are dialed into the crab and others are not -- but they're all struggling to stay afloat.

The fleet captains battle their way through a ferocious Arctic storm. Junior takes a huge risk in order to get back in the game, two greenhorns struggle to fit in with their crews, and Elliott's problems on land continue.

The crab are still not biting and desperate to make their offload dates, captains mercilessly grind their crews. But some deckhands, tired of being bullied when they're not making any cash, aren't gonna take it.

The crews and battered boats are feeling the brunt of one of the most difficult opilio crab seasons on record. While some battle potentially catastrophic breakdowns to stay on the grounds and keep fishing, others call it quits.

It's midway through the winter crab season, and the Bering Sea is taking a toll on the boats and the men. The northernmost boats are in a race to save their gear as the polar pack ice descends onto the fishing grounds.

With only three weeks left in the opilio crab season, the fleet prepares to make the final push to wrap it up. Nothing comes easy though, as the captains battle weather, equipment and their own men in their sprint to the finish.

After enduring months of mechanical breakdowns, sleepless grinds and infighting, the fleet is starting to crack. When the Wizard crew can't lasso a floating walrus carcass, Freddy Maugatai takes matters into his own hands.

The younger generation is put to the test as the fleet races to finish a grueling opilio crab season. As defiance on the Wizard turns brother against brother, an accident brings one crabber's career to a gruesome end.
